General Information
Frequently Asked Questions
CEN/TC 399 is a Technical Committee within the European Committee for Standardization (CEN). It is named "Project Committee - Gas Turbines applications - Safety" and is responsible for: Adoption of ISO 21789:2009 as a harmonised European standard,with preparation of relevant Annexes Zrelating to the ATEX, Machineryand Pressure Equipment Directives. This committee has published 1 standards.
CEN/TC 399 develops CEN standards in the area of I17 - MACHINERY IN GENERAL (INCLUDING SAFETY) - Information technology. The scope of work includes: Adoption of ISO 21789:2009 as a harmonised European standard,with preparation of relevant Annexes Zrelating to the ATEX, Machineryand Pressure Equipment Directives. Currently, there are 1 published standards from this technical committee.
The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Technical Committee (TC) in CEN is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
This document covers the safety requirements for aero derivative and industrial gas turbine prime mover applications using liquid or gaseous fuels and the safety related control and detection systems and essential auxiliaries for all types of open cycles (simple, combined, regenerative, reheat, etc.) used in onshore and offshore applications including floating production platforms.
This document applies to mechanical, electrical, and pressure equipment components and systems necessary for the functionality of the prime mover. For example, but not limited to, a core gas turbine auxiliary gearbox, an output transmission gear box, combustion system, air filtration, gas turbine controls, oil systems, and fuel system. This document also covers integration of safety risks within the overall installation, e.g. exhaust purging or drainage.
This document details the anticipated significant hazards associated with aero derivative and industrial gas turbine prime movers and specifies the appropriate preventative measures and processes for reduction or elimination of these hazards. This document addresses the risks of injury or death to humans and risks to the environment. Equipment damage without risk to humans or the environment is not covered.
The overall objective of this document is to ensure that equipment is designed, constructed, operated and maintained throughout its life in accordance with ISO 12100:2010.
This document approaches gas turbine safety from an international perspective based on the content of existing, recognized ISO and IEC standards to the greatest extent possible. Where no ISO or IEC standard exists, other codes or standards (such as EN, NFPA, etc.) have been included.
Minimum functional safety levels cannot be addressed in this document, as minimum functional safety levels are both application and site specific.
This document excludes the following items;
— exhaust-system structural design;
— driven equipment;
— micro turbines as covered by ISO 19372:2015;
— gas turbines used primarily for direct and indirect propulsion;
— gas turbines used for mobile applications;
— special heat source applications;
— gas turbines in research and development programs;
— compressed-air energy storage plants.
Where appropriate, this document can be used to give general guidance in such applications.
This document is not applicable to machinery or safety components manufactured before the date of its publication.
